Abstract: An orthodontic screw and a set of elements for forming an orthodontic or orthopedic appliance for dentistry, as well as a method for making an orthodontic or orthopedic appliance for dentistry. The orthodontic screw includes two bodies connected by positioning elements designed to allow the distance between the bodies to be adjusted; the bodies have a seat adapted to receive a portion of a connection structure associable with the orthodontic screw for its connection to the teeth of a dental arch; the seat has a groove formed on an external surface of the bodies, so that said portion of said connection structure can be inserted in the seat through a displacement orthogonal to the same seat.

Abstract: Fan screw for the expansion of the upper jaw, comprising two bodies (1, 2) connected by at least one driving screw (4; 7) and placed on opposite sides with respect to a sagittal plane (x-x), the longitudinal axis (v-v; k-k) of said at least one expansion screw (4; 7) being perpendicular to said plane (x-x), each of said bodies (1, 2) having a lingual side (L1, L2) and an opposite upper side and being provided with means for its anchorage to several teeth of a dental arch destined to be expanded. The longitudinal axis (v-v; k-k) of the at least one driving screw (4; 7) is at a predetermined distance (h) from the lingual sides (L1, L2) of bodies (1, 2), said distance (h) being measured along a lingual direction (L) parallel to said plane (x-x), such that the distance between the axis (v-v) of the at least one driving screw (4; 7) and the upper sides of bodies (1, 2) is greater than the distance between the upper and the lower sides of bodies (1, 2).

Abstract: Expansion screw for orthodontics, comprising at least one stem (1) with at least a threaded portion (10) extending along the longitudinal extension of the stem (1), at least one receiving body (3) adapted for receiving said threaded portion (10) and provided with a complementarily threaded hole allowing said threaded portion (10) to be screwed therein, guide means (2) allowing said at least one receiving body (3) to be moved, actuation means (11, 12) for actuating said stem (1). The hole (31) of said at least one receiving body (3) has a longitudinal extension substantially corresponding to that of the threaded portion (10) of said at least one stem (1). The receiving body (3) is a technopolymer receiving body and the stem (1) is embedded in the technopolymer of the receiving body when the expansion screw (100) is made.

Abstract: Orthodontic expander comprising a left frame (T1) and a right frame (T2), wherein said left frame (T1) and right frame (T2) respectively comprise a left body (1) and a right body (2) provided with means for their anchorage to the teeth of a dental arch, wherein said bodies (1.2) have through holes (10) oriented in an expansion direction (d), wherein said frames (T1, T2) are slidingly mounted along said expansion direction (d) by means of guides (4) inserted in said holes (10) of said bodies (1.2), wherein the distance (h) between the said bodies (1, 2) is adjusted by means of a screw (5) screwed into the body (2) of one of said frames, wherein said screw (5) has an operating head (51) positioned between said bodies (1.2), and wherein elastic means (M) are positioned and acting between said frames (T1, T2) and can be activated or reactivated by acting on said screw (5) which compresses them to activate or reactivate them when desired. The elastic means (M) comprise a plurality of elastic plates (6) with a curvilinear profile (P) oriented transversely with respect to said expansion direction (d).
